GONVEYER.

To all whom it may concern:

Be it known that I, JAMES R. I'IARRISON, a citizen of the United States,residing at Laporte, in the county of Laporte and State of Indiana, haveinvented a certain newand useful Improvement in Conveyers, of which thefollowing is a specification.

My invention relates to a bucket elevator, particularly such as isdesigned for handling grain or other like substances in a closed pipe.

It is illustrated in the accompanylng drawings, wherein Figure 1 is aside elevation of a conveyer with buckets of my invention in use; Fig. 2is a cross section on the line 22 of Fig. 1.

Like parts are indicated by the same letters in all the figures.

A is a tube or pipe preferably rectangular in cross section and B, Blinks of the conveyer chain.

C is the inclined bottom, D, D triangular ends and E the side of thebucket. The side of the bucket is deeply indented at F and on each sideof such indentation is a shallower indentation G. One link of the chainis provided with lateral projections J, J, which are adapted to bereceived into the indentations G, G and to be at that point riveted tothe side of the bucket by the rivets K, K. The body of that portion ofthe link which contains these lateral projections is received into theindentation F and the depth thereof is such that the outwardly extendingpart of the enlarged pivoting portions of the link are flush with themain outer surface of the side of the bucket.

By such an arrangement the chain and buckets travel in a path which issubstantially rectangle and may be of substan tially the same maximumarea as the cross section oi the pipe. In this way substantially all ofthe grain or other material to be lifted or conveyed through the pipe bythe buckets and chain is carried positively by or in front of thebuckets and there is little or no room for any such material to fall orpass from one bucket to the next. This enables me to use a pipe ofmlnimum size with maximum capacity and it prevents the slippage ofmaterial irom bucket to bucket and the loss of energy or waste efiortincident thereto.

Specification of Letters Patent.

Application filed November 17, 1913.

Patented Sept. 8,1914. Serial No. 802,176.

I claim:

1. A grain conveyer comprising a pipe, a series or buckets therein eachhaving a side approximately parallel with the adjacent slde of the pipe,a maximum cross section substantially equal to that of the pipe and achain in the pipe and outside the buckets, said chain provided withbucket attachments and said bucket side indented to receive suchattachments.

2. grain conveyer comprising a pipe rectangular in cross section, aseries of buckets therein each having a side approximately parallel withthe adjacent side of the pipe and a maximum rectangular cross sectionsubstantially equal to that of the pipe and a chain in the pipe outsidethe buckets, said chain provided with bucket attachments and said bucketside indented to receive such attachments.

8. A grain conveyer comprising a pipe, a series of buckets therein eachhaving a side approximately parallel with the adjacent side of the pipeand a maximum cross section substantially equal to'that of the pipe anda chain in the pipe outside the bucket, one end of said chain providedwith lateral bucket attachments and said bucket-side indented deeplymidway to receive the enlargements on the chain links and less deeplytoward its ends to receive the lateral bucket attachments on the links.

4. A grain conveyer comprising a pipe rectangular in cross section, aseries of buckets therein each having a side approximately parallel withthe adjacent side of the pipe and a maximum rectangular cross sectionsubstantially equal to that of the pipe and a chain inthe pipe outsidethe bucket, one end of said chain provided with lateral bucketattachments and said bucket-side indented deeply midway to receive theenlargements on the chain links and less deeply toward its ends toreceive the lateral bucket attachments on the links.

In testimony whereof, I aiiix my signature in the presence of twowitnesses this 6th day of November 1913.
